washers and types
Its shape is like a round ring. Before tightening the nut and bolt, it is placed on a stud or bolt. It is used to ensure the tightness of a connection,screw, etc. and nut bolts are easy to open and their threads are protected.
Although the fitting is slightly larger than the diameter of the bolt, the washers can be used to easily tighten the nuts.

- crescent shaped pressure washer
- lock washer
- split pressure washer
- outer toothed washer
- inner toothed washer
- torque disc

1. spring disc
This washer is in the shape of a ring cut out of spring steel. Its ends are raised slightly up and down due to spring tension. These washers are placed above or below the nut or bolt and are tightened so that their two ends are facing each other and flush.
These washers are used to prevent a nut from loosening. These are used where there is vibration or shock. This puts pressure on the nut, preventing it from turning and coming loose.
There are different shapes of spring washers. Each has its own advantages. Single pattern spring washer, pattern spring washer, double pattern spring washer, gripping pattern spring washer and protractor pattern spring washer are the structures of spring washers.
#1 Belleville washer or conical washer
The Belleville washer consists of sides that receive very high forces with small deflections. It is also known as a conical spring washer.
These washers hold an assembly in tension during thermal expansion and contraction requirements.conical washerThe deflection properties of the load depend on its height and thickness. It is used for thermal expansion projects.
#2 Dome Spring Washer
Domed spring washers are similar to Belleville washers, but have rounded sides. Belleville washers generate very high load capacities with comparatively little spring deflection.
They have rounded bottoms to form a flatter loading surface. It is used anywhere you would use a rising spring washer, but also need to create a flatter surface.
Wavy elastic sconce n.º 3
These types of washers rotate in two directions, forming a wavy shape. Spring wave washers have sufficient load and deflection capacity.
They serve as shock absorber springs or spacers on an axle. Wave spring washers have medium load capacity and deflection limits. It is most commonly used as a pad or spacer.
#4 Finger Spring Washer
Toothed washers consist of three curved tabs. Toothed washers are used to reduce damping and noise, additional wear, vibration, and sliding wear on rotating parts.
The toothed washers are made of carbon steel. They combine the flexibility of a box washer with the load points of a spindle washer.
#5 Crescent Spring Washer
These washers look like flat washers that are slightly bent to create less pressure and maintain flexibility. It is also known as a curved spring washer. They carry almost small loads with a large range of deflection.
These types of washers provide constant spring rates throughout the deflection range and have linear load deflection characteristics. Curved spring washers should be used for elastic products subjected to alternating loads. It is also used to absorb movement.
2. Lock washer
This form of spring washer is used to secure nuts and bolts. That is in many ways. Generally, six or more flakes extend beyond the major diameter of the spring washer.
After fixing this washer, its sheets are bent to the sides of the nut or bolt. Thus, this washer prevents the bolts from the nuts from loosening. This washer is generally used in cars, trucks, etc.
#1 spring washer
Split spring washers are non-continuous rings that slope each end slightly outward in opposite directions. With the lock washers in place, each end recesses into the mating surfaces. They are also sometimes called spiral discs.
This washer creates a preload on the bolt as it is tightened. The developed preload protects against loosening in case of vibration and corrosion. It is used to close a bolt.
#2 Outer toothed washer
This type of spring washer has many teeth on its outside diameter that cut into a surface and maintain compression. The external spring washer prevents the fastener head from loosening when using the reinforcing action of the teeth.
They work best with large screws. Externally serrated spring washer provides maximum resistance to twisting. Used to lock deep head fasteners in place.
#3 Internal Toothed Washer
This type of spring washer consists of many teeth on the inside diameter that cut through the nut or bolt. The internal lock washer prevents the fastener head from loosening through the supporting action of the teeth.
These disc teeth can also absorb shock and vibration. Used to lock flat head fasteners in place.
A washer is a flat disk. It has a hole in its center through which a set screw, nut or bolt can be passed. With use, the surface under bolts or nuts will soften. In this way, the pressure of the nut is uniform over the entire surface. This washer complies with the following standard:
Washer diameter = 2D + 1/8 (D = bolt diameter)
Washer thickness = 1/8 D
The chamfer angle = 30°
Inner hole diameter = screw diameter
#1 Torque Disc
The torque disc consists of a square hole and external yokes that prevent the bolt from turning when tightened. Primarily used with a carriage bolt for woodworking projects.
Flat washers are thin, flat, circular washers with a hole in the center. The use of a flat washer is intended to distribute the load over a relatively large area and provide support for small head bolts.
It is also known as a type A washing machine. A washing machine is what most people consider a normal washing machine. They are good for general use.
#3 Fender Washer
Fender washers are flat washers with a small hole and a relatively large outside diameter. Therefore, this type of washer distributes loads over a relatively larger area than flat washers.
Fender washers are used to install signs, panels, drywall, automotive, plumbing, sheet metal, and electrical applications. It is usually a thin metal. They named it so because of its common use on car fenders.
Nº 4 Clausura or Descent
The cap has a top surface designed to hold the bra. Also known as a reamer. The countersink has 90° or 120° caps.
These washers served as washers for countersunk screws. This gives the countersunk screw a level surface.
Shoulder washers consist of a shoulder type structure. They are used to protect screws, cables or other elements from the rest of the assembly. They are available in fiberglass, phenolics, nylon, PCTFE, PTFE, and metals.
They look like a flat washer, but have a slot cut into the center hole to form a "C" shape. A C washer slides in and out on the bolt or shaft.
Old C-washer may need to be adjusted or replaced without removing fastener.

The washer is a flat disk-shaped plate with a central hole. They are used to deliver cargo over a large area. Mainly used for spacers, preload bolts, springs, and vibration reduction.
